WATER-HEATER. 1

To all w hontz't may concern: i f 1 Be it known that I, WILLIAM H.FRANGIS, a citlzen of the Unlted States,resid 1ng at Galzlipolis, intheco unty of Galli'aband State of'Oh1o,have invented certain new, anduse- .t'ul "Improvements in Water-Heaters, of which the following isaspecification, reference heing had to the accompanying drawings. V e ia q s This invention relates to aAPBSGIVOiI or Water heater, adaptedparticularly for use in connection with cooking stoves and the like.

The invention aims to provide a water reservoir or heater having meanssot provided as to enable the reservoir or heater to be connected to:thefis'moke this (which carries off the products of combustion) of riveconsid'erable heat fronrthe rfiiie, for the purpose of heating the"water in the reservoir, it "being obviousthatthe water may be used forvarious (purposes.

Theinvention further, aims to providefa reservoir, simple and eflicientin construction and practical in use, and may be manufactured for smallcost and sold at ableprofit. a v v The invention further aims to afforda reservoir or heater including supporting means for the reservoir,whereby it may be supported in a superimposed spaced relation to thesupporting rneansfto provide a heating flue nn der the entire surface ofthe reser= VOiT lt being obvious that the heat may readily radiate "theEH11] area ofthe bottom of the reservoir and heat the water in thereservoir. a e a a The invention further aims to prowidea backflue(which is in communication with the bottom flue) and a top fluein comnunt; cation with the b'ackiflneywhereby the heat, which accumulates inthe bottom flue, may pass tothe rear the top, while supplying heat tothe reservoir forheating the water. i l The invention further 'ai-ms' toiprovide means carried the sirpportingwfne'mber for engagement with. thecollarat the base of theslno-ke flue, to insure a firm and close fittingconnection with the smoke -flue of the cooking stove, in-order toprevent dis placement'o'f-the reservoir. p V

, Refenring more especially to the drawings 1 designates the nnain bodyof the reservoir, which, may be constructed of anysuitable cast metal,and may be of any convenient shape or configuration, preferably such asthat illustrated. it

a a This body; in the present instance is recitangular, and its; upperportion upon each Isideof the center is open, in order to permit theentrance of water to be used. a

However the central ,part of the upper portion ofthe body is providedwith a transversely disposed plateQ, which is dished, the side flanges 3oi the central plate inclining upwardly and laterally. is obvione thatwhenthis centrally disposed plate is: covered, as will be hereinaiiterset. (forth,

a heatingflue will be constructed. The rear wall ofthe body of thereservoir is likewise dished as shown'at 4, therefore provldmgn backflue, as will be hereinafter,stated and which ;is, contiguous with thetop line, whereby the heat may .pass from one to i the other. i e i fTIhe body of the reservoir is siipported by a base member *5 whichisprovided with marginal flange 6 inclined lipwi ilfdly andim wardly. 3This marg nal flange snpports the body of the reservoir, there beingregisten i s ears 7 Mk1 16 m by th h tly nd the endparts of the marginalflange 6, for

the reception: of. securing bolts 8*, whereby i theloase or support maybe connected to the body of the reservoir. Obviously a rigid structureis afforded. The front portlon of the marginal flange 6 of the base isprov-V added with an outwardly curved U-shaped portion 9, However, wherethe U-shaped portion 9 isformed, (there'being an' ad 5 joiningbottom lOforming an integral part "of theU-sh-ape'djportion 9) an opening isformed-in thebottom for the reception of the base collar or flange 11 atthe rear of the cookin'g stove.- The bottom 10 adjacent the U-shapedportion 9 is provided with guides 12, for the reception of a slidingplate 13.

l It is clear that when the slide 13 is; inserted in its-guides, itsforward edge may contact withjthe collar 11 of the cooking stove,-thereb'y" aid in holding the base securely. in

Y position. l'Theopening 14 in the bottom-of 7 theU-shapedportion 9 maybe circular, and "of such diameter as to receive the maximum size ofsmokeflue of cooking stoves. Some smoke flues' are cylindrical andothers are "elliptical in cross-section, and" obviously by J'v-irtue ofthe'sliding plate, the supporting "base-'plateimay beceasily connectedto'a cylinfdricalor elliptical shaped smoke flue." The V 3 0outerfmarginal edgesof the U-shapedportion 9 of the flange 6is suppliedwith lateral earsf 15. The: front wallof the body of the reseryoir' isprovided with a forwardly bulgedU-shaped part 16, which conforms incontourwith the outer marginal edge of the U-shaped portion 9. Theloweredge of the U shaped part 16 is supplied with cars 17,

' which register with the ears 15, for thereeeption of suitable securingbolts, so as to Join. the Ushapedportion 9 and 16 together. A coverframe 18 is illustrated .and to be noted 'that gthe side and I endpieces 19 and 20 of thisframe are in:-

clined downwardly andfoutwardly, so as to engage the upper marginalcorner edge of the body ofthe reservoir, there being lugs 2Q carried bythe frame partially engaging 'frame lShasa transversecentrally disposedproviding a top heating flue 22, heretofore mentioned. Depending fromthe opposite fledges ofthe transverse central piece 2 1 of the frame 18are lugs 23, engaging the opposite edges of the inclined flanges 3 ofthe 7 central piece 2.of the body, in order to insure holding the'frame18" rigidly: adjoining the body; the reservoir Closure members site edes o edly connected; at 2 5. to the oppoe he i-eentral. piece 21 forclosing la .7 theupperj o'pemng's .to the mterlor of the V 5? body 'ofthe reservoir. Lugs 2'6-are formed oughly heating the water therein.shaped portion 16 forms a front vertical line on the outer ends of theclosures, to overlie the end pieces20 of the frame 18. These lugs may begrasped, permitting the closures to be raised so as to fill thereservoir. A slide plate 27 engages guides 28 on the marginal corneredges of the beveled walls of the dished part 4 of the rear wall of thebody of the reservoir, and since the upper and lower edges of the slideplate are ongaged by the top frame 18 and the supporting base, the slideplate 27 is prevented from displacement, and furthermore a rearreservoir, permitting a thorough circulation' of the heat from thebottom flue to the top flue. Rising upwardly from the bottom of thesupporting plate is a fin 29 constituting a deflector, acting to deflectthe heat to the pposite endsof the bottom flue 5, so that the heat mayradiate against the entire bot tom of the reservoir, consequently thor-The U 16 ,,which as the drawing illustrates, is in communication withthe bottom flue 5. The bottom fine is in communication with therear'flue 27 which in turn is in communication with the top heating flue22. By these various flues, itis to be noted that the central portion ofthe body or reservoir is entirely surrounded by heat, which is derivedfrom products of combustion. In other words, the products of combustionfrom the back flue of the stove are divided, a portion ascending throughthe flue 16 and the other portion is deflected by the deflector 16causing the latter portion to pass through the lines 5, 27 and 22, andthen uniting with the former portion of the products of combustion andpassing out through the flue 16. 'In order to support the reservoir inposition, it will be noted that the base member has the U-shaped portion9 of'the flange of the base member engagingthe flanged outlet of thesmoke flue of the stove, and moreover, the sliding plate 13 which ismounted in the guides 12 frictionally' is designed to clamp against theflange ofthe outlet of the smoke flue of the stove, thereby assisting insupporting the reservoir in'position. liurthermore, owing to the smokeflue 16 engaging the marginal flanged opening at theforward portion ofthe frame 18, the reservoir is additionally supported in position. Thelugs or parts 20 of the frame 18 engage within the front,

back and top flues of the reservoir, and some of such lugs 20 engagewith the inner surfaces of the end walls of the reservoir, therebypreventing movement of the top frame. In order to additionally supportand reinforce the reservoir in position, the smoke flue '16" may extendupwardly from the stove or range and then toward the wall tionally bracei't* in' "p ositio ri, "1n sup porting the reservoir. I1- d s tigeitgleee l a at the back of the stove and may be cominterposed betweenthe smoke -flue 21 and the Wall of the chimney inler yztddi suitable"suporna means (not ime be illtei'posed between the base member and thefloor that'i's atth'e roar of the reservoir,

to insure supporting the reservoirun'f place.

These features of supportingfthe' reservoir are not particularlyessentia l, since it is 0bvious that any; suitable additional supportingmeans (not shown) may beel'nployed to reinforce the heater in place. U aThe invention havmgbeen set forth, What is clalmed as new ans-useful 1s:
